Found by fuzzing with a modified fuzz-rustc

Code

The compiler panics while compiling this code (playground).

It then panics a second time while trying to explain why it panicked.

struct S<T> { _t: T }

fn f(S::<&i8> { .. }: S<&i8>) { }

fn main() {
    f(S { _t: &42_i8 });
}

I believe this is a valid Rust program, based on the variants below that compile successfully.

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.66.0-nightly (b8b5caee0 2022-10-16) running on x86_64-apple-darwin

query stack during panic:
thread panicked while processing panic. aborting.
Abort trap: 6

Variants that do not crash

It compiles successfully if I change &i8 to _ in the paramter's pattern:

struct S<T> { _t: T }

fn f(S::<_> { .. }: S<&i8>) { }

fn main() {
    f(S { _t: &42_i8 });
}

It also compiles successfully if I change the reference to specify the 'static lifetime throughout:

struct S<T> { _t: T }

fn f(S::<&'static i8> { .. }: S<&'static i8>) { }

fn main() {
    f(S { _t: &42_i8 });
}
